+## Unreleased
+- Fixes stringify to only take ancestors into account when checking
+  circularity.  
+  It previously assumed every visited object was circular which led to [false
+  positives][issue9].  
+  Uses the tiny serializer I wrote for [Must.js][must] a year and a half ago.
+- Fixes calling the `replacer` function in the proper context (`thisArg`).
+- Fixes calling the `cycleReplacer` function in the proper context (`thisArg`).
+- Speeds serializing by a factor of
+  Big-O(h-my-god-it-linearly-searched-every-object) it had ever seen. Searching
+  only the ancestors for a circular references speeds up things considerably.

+# json-stringify-safe
+
+Like JSON.stringify, but doesn't throw on circular references.
+
+## Usage
+
+Takes the same arguments as `JSON.stringify`.
+
+```javascript
+var stringify = require('json-stringify-safe');
+var circularObj = {};
+circularObj.circularRef = circularObj;
+circularObj.list = [ circularObj, circularObj ];
+console.log(stringify(circularObj, null, 2));
+```
+
+Output:
+
+```json
+{
+  "circularRef": "[Circular]",
+  "list": [
+    "[Circular]",
+    "[Circular]"
+  ]
+}
+```
+
+## Details
+
+```
+stringify(obj, serializer, indent, decycler)
+```
+
+The first three arguments are the same as to JSON.stringify.  The last
+is an argument that's only used when the object has been seen already.
+
+The default `decycler` function returns the string `'[Circular]'`.
+If, for example, you pass in `function(k,v){}` (return nothing) then it
+will prune cycles.  If you pass in `function(k,v){ return {foo: 'bar'}}`,
+then cyclical objects will always be represented as `{"foo":"bar"}` in
+the result.
+
+```
+stringify.getSerialize(serializer, decycler)
+```
+
+Returns a serializer that can be used elsewhere.  This is the actual
+function that's passed to JSON.stringify.
+
+**Note** that the function returned from `getSerialize` is stateful for now, so
+do **not** use it more than once.
